Resumen:

We investigate numerically and experimentally dynamical systems having three interacting frequencies:
a discrete mapping (a circle map), an exactly solvable model (a system of coupled ordinary differential equations),
and an experimental device (an electronic oscillator). We compare the hierarchies of three-frequency
resonances we find in each of these systems. All three show similar qualitative behaviour, suggesting the
existence of generic features in the parameter-space organization of three-frequency resonances
